King's Highway 4, also known as Highway 4, is a provincially maintained highway in the Canadian province of Ontario. Originally much longer than its present 100.8 km (62.6 mi) length, more than half of Highway 4 was transferred to the responsibility of local governments in 1998. In its present form, it travels between Highway 3 in Talbotville Royal, north-west of St. Thomas, and Highway 8 in Clinton.

Highway 4 was first designated in 1920, when a 27 km (17 mi) route between Talbotville Royal and Elginfield was assumed by the Department of Highways. Over the next half century it was extended north and east to Highway 24 near Singhampton, and south to Port Stanley.

Route Description

Highway 4 looking south towards Lambeth from the Highway 4 / Highway 402 interchange in London.

In its present form, Highway 4 travels through Talbotville Royal, Tempo, Scottsville, Lambeth, London, Northcrest, Uplands, Arva, Birr, Elginfield, Lucan, Clandeboye, Mooresville, Centralia, Exeter, Hay, Hensall, Kippen, Brucefield, Vanastra, and Clinton.

Highway 4 travels through the following municipalities: Southwold Township, London, Middlesex Centre Township, Lucan Biddulph Township, North Middlesex, South Huron, Bluewater, and Central Huron.

As of April 2008, Highway 4 officially does not exist within the City of London except south of Glanworth Drive, but instead is now signed with green "TO 4" trailblazer crown signs. The City was considering alternate routes for Highway 4 through the city in the early 2000s but this never materialized. Further north in Clinton, Highway 4 ends at the southern limits, though it remains signed.

History

The Highway 4 / Talbot Street junction in Saint Thomas.

The King's Highway 4 was originally designated in 1920 when the provincial government assumed the road running from Talbotville Royal to Elginfield through London. In 1927, the highway was further extended with the assumption of the road from Elginfield to Clinton. In the 1930s, the highway was again extended as far as the intersection of Highway 10 in Flesherton. In the 1970s, Highway 4 reached its maximum length when it was extended from Flesherton to Singhampton. However, in 1998, the Mike Harris government, seeking to balance the provincial budget, off-loaded responsibility for the Clinton–Singhampton section of Highway 4—almost 65% of its total length—back onto municipal governments.
